Abstract: Embodiments of the present application provide communication methods and systems. One method comprises receiving, from a first access network device, signaling destined for a terminal device, wherein the terminal device is in a radio resource control (RRC) inactive mode. A first paging message is sent to a second access network device for paging the terminal device and first indication information is received indicating that the terminal device is connected to a second access network device. After receiving the signaling destined for the terminal device, the first access network device can learn the terminal device has connected to the second access network device, and therefore performs proper subsequent processing.

Abstract: System information block transmission methods and communication apparatus are provided to resolve a problem that a terminal device cannot receive, on an active bandwidth part, a system information block broadcast by a network device. A network device sends a system information block to a terminal device through a first bandwidth part. When determining that a first moment satisfies a preset condition, the network device sends the system information block to the terminal device through a second bandwidth part, where the system information block is included in first dedicated signaling, and configuration information for sending the system information block by the network device is not configured on the second bandwidth part.

Abstract: This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A terminal device receives first indication information, where the first indication information indicates a target monitoring occasion of first control information, and then, the terminal device may monitor the first control information on the target monitoring occasion, where the first control information is used to schedule information about a multicast service. The target monitoring occasion includes at least one of a plurality of monitoring occasions of the first control information. In this manner, an access network device sends the first indication information to the terminal device to indicate the target monitoring occasion, so that the terminal device can perform monitoring on the target monitoring occasion. Compared with a manner in which a terminal device performs monitoring on a plurality of monitoring occasions of first control information, this manner reduces unnecessary monitoring.

Abstract: A method and an apparatus are provided. The method includes: An access network device sends DCI for a paging message to a terminal device, where the DCI includes scheduling information for downlink data. The access network device further sends first indication information included in the paging message to the terminal device, wherein the first indication information indicates that first downlink data corresponds to the terminal device. Therefore, when determining that there is downlink data to arrive, the terminal device determines a time-frequency location of the downlink data based on the scheduling information that is for the downlink data and that is in the DCI, and then receives the downlink data at the time-frequency location. According to the method and the apparatus provided in this application, a small amount of downlink data is transmitted, resource utilization is improved, and power consumption of the terminal device is reduced.
